摘　要:采用聚四氟乙烯（PTFE）表面特性实验和列斯实验,研究了空气电极表面的渗液机理。得出的初步结论是：在所有的电介质中,电渗现象表现得最为强烈的是KOH;在KOH溶液中浸泡后,PTFE膜的疏水性会显著降低,使得电渗更容易发生。[著者文摘]

The mechanism research of seepage on the surface of air electrodeYANG Yong-qing, XU Xian-zhi, PAN Kui Department of Modern Mectianics, University of Science and Technology of China, Hefei, Anhui 230027, ChinaAbstract:The seepage mechanism was researched in PTFE surface property experiment and ramirez experiment. The preliminary conclusion was made： it was the KOH which made the strongest eleetroosmosis phenomenon in all conducting mediums. The hydrophobicity of PTFE film was decreased dramatically after immersing in the potassium hydroxide solution, which could lead to the electroosmosis phenomenon easily.[著者文摘]
